MAGAZINE NAILING-TOOL.

Specification of Letters l atent.

Application filed February 14, 1911. Serial No. 608,507.

To all 107mm it may concern:

Be it known that I, ISAIAH J. BRowN, a citizen of the United States ofAmerica,,residing at Jersey City, in the county of Hudson and State ofNew Jersey, have invented certain new and useful Improvements inMagazine Nailing-Tools, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to a nail or tack driving tools, such ashat-chets, hammers, and the like, and the principal object of the sameis to provide a ma azine driving tool in which the nails or t-ac (s arefed through the handle of the tool and the driving head thereof. By theemployment of novel setting means which are controlled by the user, thetacks are quickly and singly set in position to be driven into holdingpositions.

In carrying out the objects of the inventiondgenerally stated above itwill be understoo of course, that the essential features thereof aresusceptible of changes in details and structural arrangements, onepreferred and practical embodiment of which is shown in the accompanyingdrawings, wherein Figure 1 is a vertical longitudinal sectional view ofa hatchet constructed in accordance with this invention, the bladethereof being shown in elevation. Fig. 2 is a transverse sectional viewtaken on the line 2-2, Fig. 1. Fig. 3 is a similar view taken onthe-line 3-3, Fig. 1. Fig. 4 is a detail transverse sectional view takenon the line 44, Fig. L Fig. 5 is a fragmentary detail View in elevationof the thumb operated trigger for controlling the setting implement.

For illustrative purposes, and as a showing of one practical use of theinvention thesame has been shown in the accompanying drawings as ahatchet such as is commonly used by lathers.

Referring to the said drawings by numerals,-6 designates the usualblade, 7 the driving head, and 8 a hollow tubular handle which ispreferably integral with the head and blade. Said handle has a lid orcover 9 for its open rear end that is hinged to a pivot stud 10 in arecess 11 in said rear end.

. The hollow handle 8 is provided with a longitudinally extending baseguide slot 12 that extends to and is in communication with 'the innerend ortion of a discharge passage 13 that exten s longitudinally throughthe head 7. The rear end wall 14 of the slot-12 is rounded to provide agnideway to cause the shank of the nail or tack to enter said slot 12.Slot 12 is wide enough to permit the shanks of the nails or tacks to befreely moved therein, but too narrow to permit the heads thereof toenter said slot. Adjacent the'driving surface, head 7 is provided withan inclined transverse opening 15 the inner end of which is incommunication with passage 13 and is disposed opposite and in UNITEDSTATES PATENT OFFICE.

alinement with a side recess 15 of said passage 13.

At an intermediate point the handle 8 is provided with a pendent housing16 the forward end wall of which is provided with an inclined opening 17that is in alinement with the opening 15 of head 7. The rear end'portion of the housing 16 has an opening 18 through its bottom that isin alinement with a recess 19 in the top of said housing. A guidingsleeve 20 extends through opening 18 and has its inner end seated inrecess 19. The flanged head 21 is counter-sunk in the opening 18. Sleeve20 has its body provided with a longitudinal slot 22 and adjacent theouter end of said slot, a pin 23 extends transversely through saidsleeve. A thumb operated trigger, which is in form of a bolt, has itsshank 24 longitudinally slidable in sleeve 20, said shank being providedwith a longitudinal slot 25 through which pin 23 extends for limitingthe sliding movements of said trigger. An enlarged and preferablyflattened head 26 is provided for the shank 24, said head being at alltimes projecting outward relative to the bottom of the housing 16 sothat the same is accessible to the fingers or thumb of the user of thetool. A spiral spring 27 is inclosed by the sleeve 20 and 1s interposedbetween the shank 24 and the top of the recess 19 and exerts a tensiontending to retain the trigger at the limit of its outward movement.

A casing 28 is provided between head 7 and the forward end wall ofhousing 16, and

the inclined bottom 29 of said casing provides a slideway betweenopenings 15 and 17 At an intermediate point, the slideway 29 carries anarched spring seat 30 the flanged rear end of which is provided with atransverse guide opening 31. A rod 32 is slidable through the opening 31and its rear end carries an abutment collar 33 that contacts with theouter surface of the rear end of the spring seat 30 to limit themovement of said rod in one direction. The for ward end of rod 32 isthreaded for engagement with the threaded socket 34 in the rear end of acombined cut-ofi andnail setter 35 that is slidable through opening andhas a flattened end 36 for engaging the about it, one end of which bearsagainst the rear end of the combined. cut-off and setter and the otherend resting in the spring seat 30. The tension of spring 37 isconstantly exerted to retain the cut-ofi and setter across the passage15.

The end collar 33 of rod 32 has one end of a cable 38 fastened thereto,said cable extending into housing 16 through the end opening 17 andpassing about idler pulleys 39 and into sleeve 20 through the slot 22therein and being suitably fastened to the shank 24 of the thumboperated trigger. The tacks are held by any suitable means in positionbeneath the plunger before being driven-in place.

In operation, the tool is charged by placing the nails or tacks in thehollow handle 8 and sealing the said handle by means of the end closure9. The nails feed through the handle-and enter the guide slot 12 and.slide 'along the same to the passage 13 of head 7 until said passage isfilled. The cut-off and setter 35 is normally held across the base ofpassage 13 by the tension of spring 37 so that but one nail at a time isin position to be set. When the-initial nail has been set, the trigger24 is forced inward by thumb pressure against the tension of spring '27causing cable 38' to retract the combined setter and cut-off against thetension of spring 37 so that the next nail will drop to a settingposit-ion. The thumb pressure on the trigger 24 is then released,

f and the tension of spring 27 forces the trigger 24 outward so that thestrain on the cable 38 is removed, whereupon the spring 37instantaneously slides. the cutbfi and setter I across passage 13,toprevent the inner nails dropping and at the same time, the flat. endof said cut-ofi' and setter contacts with the head of the outermost nailand firmly sets the same in the work. This operation can be quickly andconstantly repeated so that a row or rows of nails can be set in thework and afterward firmly driven to holdextending passage formedtherethrough,

said head being also provided with a trans verse passagewaycommunicating with said longitudinal passage, and with a seat formed in,alinement with .said transversely extending passage, a hollow handleextending from said head and communicating with said longitudinalpassage, a housing formed between said head and handle, the bottom ofsaid housing being in alinement with said transversely extendingpassageway, a plunger passing through said transversely extendingpassageway,, and into said seat, means in said housing for normallyholding said plunger within said seat, and means for drawing saidplunger into said housing to form a clear passage through said head.

2. A device of the character described comprising a head having alongitudinally extending passageway and a transversely extendingpassageway intersecting said longitudinally extending passageway, aplunger slidably mounted in said transverse passage and extending acrosssaid longitudinal passage, a hollow handle extending from said head-andcommunicating with said longitudinal passage, a housing formed upon saidwhich said pin passes, a spring mounted in said sleeve beneath saidplunger and a cable connected with said plunger at one end and at theother end with saidfirstmentioned plunger, whereby said first mentionedplunger may be drawn through said transverse passage.

In testimony; whereof I hereunto aflix my signature in presence of twowitnesses.
